Biosynthesis of Major Reactive Oxidative Species

The video discusses the biosynthetic pathway of reactive oxidative species (ROS), highlighting their formation, roles, and impact on cells. It explains how ROS, primarily originating from molecular oxygen, can lead to free radicals that damage proteins, lipids, and DNA, potentially causing cancer. The video also covers the protective role of enzymes like catalase and the destructive mechanisms involving myeloperoxidase and the Fenton reaction in immune cells. Additionally, it explores reactive nitrogen species and their regulatory functions in protein activity.
